Just measured my TA a couple of times and it is reading 50. Other readings are:
CYA = 50
FC = 6
PH = 7.5
CH = 450
Pool is IG plaster 38000 Gallons.
Pool calculator is saying to add 16 Pounds of baking soda to get to TA = 100. How much should I add at a time and what is the best way to add it, broadcast or into the skimmer?
